Following Thanksgiving dinner, your uncle falls into a deep sleep while sitting straight up and facing the television set. In this case, we can express the conservation of angular momentum as IiiIffconstant Doesnt friction affect its motion?

Solutionobtain A BUsing Equations Instead, the order in which the two vectors are multiplied in a cross product is important: The rst comes from the law of the conservation of linear momentum: How does the torque on the reel change with time? However, the net torque associated with all internal forces is zero. The woman then starts walking around the rim clockwise as viewed from above the system at a constant speed of 1.

Find the minimum value of v such that the cube falls off the table. Referring to Table Air drag and friction associated with deformation of the ball eventually stop the ball. The angular speed of the skater increases when the skater pulls his hands and feet close to his body, thereby decreasing I.

ERMETE TRISMEGISTO LIBRI PDF The top would certainly fall over if it were not spinning. You can use v to determine the direction of L r p because the direction of p is the same as the direction of v.

### Movimiento Rotacional y Momento Angular

However, we can simplify matters by restricting rotacionap discussion to a homogeneous rigid object having a high degree of symmetry, such as a cylinder, sphere, or hoop. The bullet becomes embedded in the cube. It is left as an exercise to show from Equations Some properties of the vector product that follow from its denition are as follows: Because none of the boxs initial potential energy is converted to rotational kinetic energy, at any time t 0 its translational kinetic energy is greater than that of the rolling ball.

Its motion is constrained by a brake at B so that its radial speed remains constant. A rigid, massless rod has three equal masses attached to it, as shown in Figure P The period is the lengthSolution 30 days 2. Just as the idea of linear momentum helps us analyze translational motion, a rotational analog angular momentum helps us describe this skater and other objects undergoing rotational motion. Two particles of masses m 1 and m 2 are connected to its ends.

The moment of inertia of a solid sphere about an axis through its center is, from Table What is the torque about a the origin and b the point having coordinates 0, 6 m? Again, the force n exerted by the support on the axle produces no torque about O, and the force of gravity Mg produces a torque of magnitude Mgh about O, where the axle is perpendicular to the support. A bullet of mass m traveling parallel to the horizontal surface and normal to the rod with speed v hits the block and becomes embedded in it.

## 11-Movimiento Rotacional y Momento Angular

In this case we express the conservation of angular momentum in the form Li Lf constant Solution You might guess that because the linear momentum of the particle is always changing in direction, not magnitudethe direction of the angular momentum must also change.

The cylinder is initially at rest and is mounted on a xed horizontal axle that runs through the center of mass. This is the total external torque about the pulley axle; that is, ext m 1 gR. Hence, the axle moves in the direction of the torque that is, in the horizontal plane.

Find the minimum value of v required to tip the cube so that it falls on face ABCD. Express the work in terms of M and v. A spool of wire of mass M and radius R is unwound under a constant force F Fig.

Now let us differentiate Equation
